The output of the following combinational circuit
- A.
X.Y
- B.
X+Y
- C.
X ⊕ Y
- D.
(X ⊕ Y)’
Attempted by 45 students.
Show answer & explanation
Correct answer: D
The circuit consists of three NAND gates. The first two gates receive inputs X and Y, producing outputs (XY)'. These identical signals feed into the final NAND gate. The output is ((XY)' · (XY)')', which simplifies to XY via double negation. Thus, the circuit functions as an AND gate.
